An Advanced Creature Profile by Vincent Groth.  

The Orc stands an average of six feet tall and is made of thick green skinned muscle. Orcs are made from wicker mannequins or other organic materials made into vaguely humanoid shape, they can reproduce, female orcs can function outside of the horde. Male Orcs tend to be warped, misshapen, and twisted their extreme muscle growth too fast for their skeletal structure and skin to keep up. Female Orcs however do not undergo rapid growth that devastates their bodies they tend to be strangely beautiful as Haltheris tends to make most of his feminine brood to protect the species as conquerors of Orc tribes might take them as mates. Orcs tend to have black hair on their scalps but rarely grow body or facial hair. 

Orcs are far stronger than their already large frames appear. Male Orcs can easily overpower a normal man in feats of physical strength. Orc blood is thick and seals wounds rather quickly and at least males grow at alarming rates coming to full physical maturity within a few years; they also never top growing until their organs fail to maintain their growing hulks. Orcs can reproduce with almost any humanoid species make and female orc genetics overriding much of the genetic material of their partners. Female Orcs are capable of manifesting magic. 

Orcs serve as the main fighting body of the Greenskin Horde and the main body of the horde entirely. Orcs are the face of the Horde. 

The Orcs are vulnerable to fire, salt, and holy energy. They are rather dim and come at problems head on. Male Orcs are barely sapient.
